Dosatron - Hobby Cultivator System - 5 GPM (3/4 in) (HYDRO)

Brand: Dosatron

The Dosatron Hobby Cultivator is a compact, water-powered nutrient delivery system for small-scale indoor growing. It uses the same proportional dosing technology as Dosatron's commercial injectors, scaled down: water pressure alone drives the dosers, and each one draws concentrate in fixed proportion to the water flowing through it. Nutrients stay at the set strength with no hand-mixing, no electricity, and no batch tanks.

The standard system ships with four dosers on a shared manifold, enough to run a four-part feed program straight into the irrigation line. It suits direct injection, deep-water culture, ebb and flow, and most other hydroponic methods, and can be expanded by adding dosers as a feed recipe grows.

Hydro vs HORT Versions

This is a Hydro (HY) build. The dose scale is marked in mL/gal alongside percentage and ratio, and union connections are included so the dosers install in series as part of a nutrient delivery system.

Service and Maintenance

These dosers are field-serviceable and designed to be rebuilt rather than replaced. Plan on an annual seal replacement and periodic irrigation line cleaning. Install a strainer ahead of the system and flush after dosing aggressive chemistry to get full service life.

Ideal Applications

• Small-scale indoor cultivation
• Multi-part feed programs at hobby scale
• Propagation benches and single-room grows
• Herbs, leafy greens, fruiting and vegetable crops
